Short cut for gsub("word","")

ruby-talk

is there any shortcut for removing a string of characters from text,
like gsub("word",""). I looked into String#delete but it will delete all
the characters in the entire word.

Im guessing something like this already exists.

I'm kind of surprised String#- doesn't work (it isn't defined)

  str["word"] = ""
  str[/word/] = ""

but these only do the first instance.

If you find yourself writing

  str.gsub! /word/, ''

repeatedly, to the point where it is tiresome, then factor it out
yourself, depending on exactly what your needs are. e.g.

  class String
    def remove!(str)
      gsub!(str, '')
    end
    def remove(str)
      res = dup
      res.remove!(str)
      res
    end
  end
